Wheel-type wide-width precision seeding device

Abstract

The invention provides a wheel shaft type wide-width precision seed distribution device, which includes a box body, an inner core, a seed discharge port and a seed distribution pipe, the inner core is cylindrical, the inner core is located inside the box body, and the Both ends of the inner core are connected to the box through bearings, the outer surface of the inner core is provided with evenly distributed concave and round dimples, and a row of brushes is arranged inside the box along the axial direction of the inner core, and the brushes and the The inner wall of the box is threaded, the seed discharge port is located at the bottom of the box, the seed distribution pipe is located below the seed meter, the seed distribution pipe includes a seeding trough, and the seeding trough is connected to the The seed discharge port is connected, and the seed distribution pipe is arc-shaped, and the arc angle is 40°≤θ≤50°. The seed distribution tube is arc-shaped and has a certain angle with the ground, which slows down the landing speed of the seeds, prevents the seeds from bouncing after landing and deviates from the sowing point, and improves the sowing accuracy. It can be seen from the above that the present invention solves the problem of seed bouncing in the background technology, and is simple and practical.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding equipment, in particular to a wheel-axle type wide-width precision seed distribution device. Background technique [0002] The seeder is a kind of planting machinery used for crop seeding. It is the main machine tool for farmland operations and plays an important role in agricultural production. As the key part of the seeder, the seed distributing device directly affects the working quality of the whole seeder. [0003] The precision seed distribution device can achieve the goals of uniform seed distribution, uniform seedlings, seed saving, and increased production. It is the main development direction of the future seed distribution device. There are dozens of seed distribution devices on the market, which is enough to show that Seeing the importance of seeding devices for sowing, there is still a lot of room for improvement in my country's seeding devices. [0004] The current prec...

Problems solved by technology

[0005] Although there are many types of seed distribution devices, the seed pipes of most of the seed distribution devices are set vertically on the ground. The seeds fall vertically from the seed distribution device, and the landing speed is too fast, causing the seeds to bounce and deviate from the sowing point, affecting the sowing precision
